>> she offered to give him a ride? >> they came together. >> then what happened? >> she didn't go to work, nobody could find her. >> when did you get the feeling something was wrong? >> when she didn't show up to her doctor's appointment in the afternoon. i called her boyfriend and told him to meet me at the police station. >> reporter: hours later, they find her car, destroyed by fire in an isolated, wooded area, just off the road. >> with the burned-out vehicle, no telling what you're going to find if anything. high heat will destroy any dna for the most part. any fingerprints would probably be gone, anything like that. >> reporter: there's no sign of jessica inside. >> that was my worst fear, that she was burnt inside. >> reporter: a search party scours the woods and comes up empty. >> it's suspicious circumstances to find her vehicle burned,
unkoupped in a remote area. >> reporter: early the next morning, kyler is arrested, accused of setting her car on fire, charged with knowingly burning a vehicle. he's pleaded not guilty. denying any involvement with her disappearance to 41 action news. >> kyler, where's jessica? >> i have no idea, sir. >> reporter: kyler had a troubled childhood. court documents allege that he was physically and sexually buys abused as a child and that he drank and started doing drugs at age 12. if you could talk to him, what would you say to him? >> just tell me where my daughter is. i don't care about anything else. i just want to know. >> reporter: molly hastings is her lawyer. jessica's mother is begging him to speak out, but you've advised him not to. >> any attorney worth their salt would give him the same advice. and this is not advice to further punish or penalize jessica's family. kyler has not been charged with anything outside of knowingly burning this car, and that
again, a charge we've pled not guilty to, and that we intend to fight. >> reporter: kyler used is still in jail, awaiting trial for charges related to the burning of the suv. he's never been charged in her disappearance. but were there disturbing signs in his past? >> the court documents show an escalation of violence. >> any time you have domestic violence, there's an escalation. >> reporter: in 2011, an ex-girlfriend sought an order of protection, alleging he punch, clapped, and choked her, saying he threatened to kill her and her baby. but what happened to his other girlfriend ten years ago is most alarming. >> she was 17 when she went missing, kara. >> kara loved her friends, loved being around people. she always had a -- she had a smile. >> reporter: her parents say they noticed a personality change aer

and they haven't. and it's been ten years. >> and yet ten years later, he's still a person of interest in that case. >> i think he will be a person of interest forever, based on the fact that public opinion has already made up its mind. >> reporter: for police lieutenant brad swanson, kyler has stuck with him for nearly a decade. >> at the time of her disappearance, this was the high school. >> a decade later, kyler is distill a person of interest? >> yes, you can say that. he's been able to eliminate a lot of people, we haven't eliminated kyler. >> that doesn't make him a suspect? >> correct. >> this is where we meet once or twice a month. >> reporter: but for jamie, it's not about kyler, it's about answers, and bringing together a community of support. >> 40 of us get together, we brain storm, hit the maps, talk about the maps. >> reporter: the garage, now a make
headquarters. >> we took over a hundred people in the first three weeks. we cleared from the back part all the way up to the housing. >> reporter: the search is a family affair. jessica's father, john michael runions, searching with his team. jessica's grandfather is also wanting this nightmare to end. he often searches for jessica at night, driving the same route he thinks she would have taken after that party. >> the hardest problem is, there's no closure. that's the thing. everybody's looking for a little closure. jamie's pretty strong, but eventually there's a time when jamie is -- it's gonna hit her and hit her hard. >> are you afraid of what you could find? >> it will be hard. but the thing of it
found her. either way. i mean, it will be hard. but the thing of it is, is, my wish will come true, her nightmare will be over, and she will be with us, no matter what. >> reporter: a wish now shared by these two families, united in grief, still searching for answers. for "nightline," i'm juju chang in kansas city, missouri. >> our thanks to juju for that report. coming up next here, something very different. is boxing the new yoga? why more and more women are going the distance. and later, the unlikely friendship between george w. bush and michelle obama. in my asthma treatment with breo. once-daily breo prevents asthma symptoms. breo is for adults with asthma not well controlled on a long-term asthma control medicine, like an inhaled corticosteroid. breo won't replace a rescue inhaler for sudden breathing problems. breo is specifically designed to open up airways

and what if this happened again? i was given warfarin in the hospital, but wondered, was this the best treatment for me? so i asked my doctor. and he recommended eliquis. eliquis treats dvt and pe blood clots and reduces the risk of them happening again. yes, eliquis treats dvt and pe blood clots. eliquis also had significantly less major bleeding than the standard treatment. both made me turn around my thinking. don't stop eliquis unless your doctor tells you to. eliquis can cause serious and in rare cases fatal bleeding. don't take eliquis if you have an artificial heart valve or abnormal bleeding. if you had a spinal injection while on eliquis call your doctor right away if you have tingling, numbness, or muscle weakness. while taking eliquis, you may bruise more easily ...and it may take longer than usual for bleeding to stop. seek immediate medical care for sudden signs of bleeding, like unusual bruising. eliquis may increase your bleeding risk if you take certain medicines. tell your doctor about all planned medical or dental procedures. eliquis treats dvt and pe blood clots.

reagan's memorial. i can't remember where else i sat next to her, i probably have a few wise cracks, she seemed to like it okay. >> reporter: even a staunch socialist couldn't help chuckle at bush versus poncho at inauguration day. a 17-year gap and a political chasm. >> they're interested also in doing things with our troops, in their after life, as i call did. >> reporter: bush 43 promoting his books of paintings of post 9/11, war veterans. >> it's going to take them a while to find their footing, figure out how they're going to do what they want to do. >> reporter: recently revealed, the letter from bush 41 to bill, i am rooting for you. can we all learn a lesson from that? and this. i'm nick watt for "nightline" in los angeles. >> our thanks to nick and to you for watching abc news
